feat(backends): add darwin/metal build for liquid-audio (#10486)

* feat(backends): add darwin/metal build for liquid-audio

Wire the already-MPS-ready liquid-audio backend (it ships
requirements-mps.txt) into the darwin CI matrix and the gallery so
metal-darwin-arm64 images are built and selectable.

* ci(liquid-audio): trigger darwin build via requirements-mps note

The changed-backends path filter only builds a backend when a file under
its directory changes. The metal wiring lived in index.yaml + the matrix,
so the darwin job was skipped. Add a documenting comment to the MPS
requirements so CI actually exercises the darwin build.

* fix(liquid-audio): guard uv-only --index-strategy for the pip/darwin path

Same fix as trl: the darwin/MPS build installs with pip (USE_PIP=true), which
rejects the uv-only --index-strategy flag and failed the darwin backend build.
Add it only on the uv path; Linux/CUDA resolution is unchanged.
